Hi, I updated my system from fedora core 1 to fedora core development. I first upgraded some packages (python, xorg, yum, openoffice.org, some gnome packages...). When I did a yum update for the remaining packages, and there was still a lot to update, with the proper --exclude, yum said that I needed something like 260 Mo. However I was able to realise an update, not for all the components at one time but choosing subsets, like yum update 'a*' 'b*' 'c*' 'd*' 'e*' 'f*' And now that I ran the final yum update, I have about 300M free on my /, which contains everything except /home and /opt. The only thing outside of the / is /var/cache/yum, it is a link /var/cache/yum -> /opt/fc1t/var/cache/yum/ and /opt is on another partition. Thus, it seems that with that setup, yum didn't compute the disk space right. Pat
